Trump immigration: Texas sends National Guard to Mexico border

The US state of Texas is deploying National Guard members to the border with Mexico following a call from President Donald Trump. President Trump says he wants to send up to 4,000 National Guard members to secure the border with Mexico, until his proposed border wall is built. Mr Trump also threatened Mexico, saying the North American Free Trade Agreement was at risk unless it stopped the movement of migrants over the border. The president has called sending troops to the Mexico border a "Big step", but both his predecessors also dispatched the National Guard there. In December, US Border Patrol announced arrests at the southern border had fallen to their lowest level since 1971, apparently indicating that fewer people were attempting the crossing.
